Urgent helpp

DDDDDDDDDDDDDD 2. A research team took a random s. or 348 observations from a bivariate normally distributed random variable (Y, X), with population correlation coefficient p. They observed 1348 = 281.1, with an observed standard deviation of 21.7 (the divisor in the underlying variance calculation was n -1). They observed X348 = 78.2, with an observed standard deviation of 41.5 (the divisor in the underlying variance calculation was also n - 1). The Pearson product moment correlation coefficient between the two variables was 0.48. Find the 99% confidence interval for p. This problem is worth 5 oints
